Acontainer of gas molecules is at a pressure of 2 atm and has a mass density of 1.7 grams per liter. all of the molecules in the container are diatomic nitrogen molecules with an atomic weight of 28 grams per mole. what is the average speed of the nitrogen molecules in the container? here we define the average speed as the root-mean-square velocity (rms velocity = vrms) of the center of mass of the molecule.

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
